I was looking for a receiver block to hold the buffer tube during installation and the only other one was always out of stock and way too expensive. Then I found this one and it is perfect for the application. cost is great and it works like a charm. It is well worth the cost for the convenience of helping with assembly. I'm sure I haven't discovered all the benefits yet but I'm sure it will become a highly used tool.
I find this product to be great!!! It’s just what I needed for my project, and I highly recommend this to everyone!!!!! Thank you again Botach!!!!!!
If your thinking about building your own at-15, do not pass this up, not all buffer tubes come with an anti rotation cut for the buffer detent no matter how cheap or expensive so if you don’t want to risk the tube rotating and the end plate messing up the threads when torquing 40 foot pounds please buy this, you will not regret it, screws are polymer and will not scratch your tube, just slide in easy and steady, also make sure you clamp down pretty good with your vise to avoid this tool from moving.
This is a well made tool that is essential for no fuss tightening of the castle nut. With some 0.012" aluminum sheet I cut two 0.75" x 3" strips, smoothed the edges and then bent each piece into the same curve as the buffer tube. Putting each strip between the buffer tube and the bench block gave a nice snug fit and protected the buffer tube finish from the inside edges of the bench block. This is not at all needed, as the block works perfectly otherwise. Shipped quickly as well.
Price, Quality, ease of use deserve 5 stars....no complaints! I’ve built 16 lowers so far and it does what its supposed to!
Exactly what I needed, exceeded my expectations.
Fantastic product!!!!!!! If you don't have one buy this one you want be disappointed.
Fantastic tool easy to use and does the job without damage to the receiver.
I was able to easily torque my AR receiver buffer tube to the specified 40ft pounds without twisting the receiver plate and stripping the buffer tube threads. Worked just as it was advertised. I would highly recommend this without any hesitation.
This tool serves a single purpose and it works. Simple as that. Zero complaints and it gets the job done. Unless you just have to have a name brand, there's no need to spend the extra money. Buy with confidence.
Solid tool, not sure what else you would need from it. Maybe two more screws on the other side? Worth the price!
